I know its a little over budget, but you will be hard pressed to squeeze out much less, obvious areas are RAM, CPU, and case, those three could probably drop you down, but you would sacrifice performance and quality that way, I would recommend spending the extra $30 on the builds.

For your PC, you mentioned you need wireless internet;

LINKSYS WMP54G IEEE 802.11b/g, PCI 2.2 and 2.3 32bit PCI2.2 Wireless-G Adapter Up to 54Mbps Wireless Data Rates WEP, WPA, CCX 2.0 - Retail

Thanks! Where does that wireless adapter install? And 532.00 isn't too bad, it's very manageable. I appreciate the advice.

One other question, will I have any problems running my 37" LCD tv as my monitor? I'm about to buy the cable to do it but will it affect anything as far as gameplay?

EDIT: Also, my Dell PC has a CD/DVD drive I bought for about 20 bucks. Could I salvage that and save the 20-30.00?

The wireless adapter installs in a PCI slot in your computer, of which you have plenty =)

Is your 37" TV 720P or 1080P, the games you mentioned are not very graphically demanding, and at 720P resolutions, the HD4850 would be perfect. At 1080P, you will be fine running most games, just not maxed out games, this however applies to new and current titles like Fallout 3, Second Life will run perfectly.

You can definitely use that optical drive from your dell.

Thanks Transmaniacon! A couple more questions:

My girlfriend wants a pink case lol, is this one decent? http://www.directron.com/atx927wk.html?gsear=1

And for me to have USB ports, will I have to add those? Or will they already be in the case when I get it? I'll need a few for mouse/keyboard obviously, and then an extra for stuff like ext. HD and ipod and what not. thanks!

That one isn't bad, RAIDMAX usually makes decent low end cases, and they try to offer a lot of features and appearances not available at those price points.

The motherboard I linked earlier has 8 USB 2.0 slots, and the Antec 300 case has 2 on the front.

There should be some in the front of the case, and more on the back of the motherboard

Thanks guys! another question on OS's. I'll probably get Vista since it's probably cheapest, but my girlfriend is a Mac person. Can she get install the Mac OS on hers and everything be fine? She's never owned a non-Mac and apparently doesn't want to start now haha.

Installing a Mac OS on non-Mac hardware is technically illegal. Posting about that is against the Tom's forum rules. You'll have to spend some quality time on Google to figure that out on your own.  

Ah gotcha. reading reviews, I'm concerned that graphics card will burn up. Is that an issue where I might be better off with a different, more reliable one?

The dual-slot coolers on the XFX cards exhaust the heat outside the case, but they cost a little more.

Okay so for the XFX card, which requires 450W of power, would this be a good PSU? http://www.newegg.com/Product/Product.aspx?Item=N82E168...

That PSU would be fine.
